Access and audit

People use roles and attributes. Applications use scoped keys. Policies decide whether a requested action is allowed in its current context. Approvals introduce a deliberate human decision when risk warrants one.

Record security-relevant events-access changes, key creation and rotation, policy decisions, approvals, and actions-in an append-only audit trail. An audit record should identify the actor, target, decision, time, and correlation identifiers needed to connect it to a run.
